Advanced Information

PRELIMINARY

The RAC pin remains HIGH for 500 µsec and stays LOW for 15.6 µsec under the Message Cueing

mode. See the Timing Parameters table on page 55 for RAC timing information at other sample rates.

When a record command is first initiated, the RAC pin remains HIGH for an extra TRACLO period in

order to load sample and hold circuits internal to the device. The RAC pin can be used for message

management techniques.

INT (Interrupt)

INT is an open drain output pin. The Winbond I5216 Interrupt pin goes LOW and stays LOW when an

Overflow (OVF) or End of Message (EOM) marker is detected. Each operation that ends in an EOM or

OVF generates an interrupt, including the message cueing cycles. The interrupt is cleared by a READ

STATUS instruction that gives a status byte out the SDA line.

MCLK (Master Clock Input)

The Master clock input for the Winbond I5216 product has an internal pull-down device. Normally, the

Winbond I5216 ChipCorder section is operated at one of four internal rates selected for its internal

oscillator by the Sample Rate Select bits. If the internal oscillator is powered down (configuration bit

OSPD set to ONE), the device is clocked through the MCLK pin as shown in the section I5216 Analog

Structure (right half) description on page 36.
